Referring now to FIG. 1, an embodiment is shown of a door handleassembly 10 for a motor vehicle. The door handle assembly 10illustratively includes a grip cover 12 that mates with a handle base14. The handle base 14 illustratively includes a pivot mount 18configured to be pivotally mounted to an entry door of a motor vehicleand a latch actuator 16 operatively coupled with a door latch assemblylocated within the entry door. Together, the grip cover 12 and thehandle base 14 form a grip configured to be grasped by a human hand. Aswill be described in greater detail below, the grip cover 12 and handlebase 14 together form a housing which carries two sensors; one which maybe triggered or otherwise activated to cause a door latch of the entrydoor to lock and thereby prevent manual actuation of the handle assembly10 to open the entry door and/or to latch the handle assembly 10 to theentry door, and another which may be triggered or otherwise activated tocause the door latch of the entry door to unlock or unlatch so that thedoor handle assembly 10 may be manually actuated in a conventionalmanner to open the entry door.

In the illustrated embodiment, the grip cover 12 comprises opposingupper and lower walls 12A, 12B respectively and opposing side walls 12C,12D respectively. All such walls 12A-12D are joined by an elongated andfront wall 12E which may be at least partially arcuate. Between the sidewalls 12C, 12D, the upper and lower walls 12A, 12B of the grip cover 12define a rear lip 12F which illustratively defines an arcuate andgenerally concave section 12I between and relative to two opposing endsections 12G, 12H (see FIG. 6). Between the rear lip 12F and interiorsurfaces of the upper and lower walls 12A, 12B, the side walls 12C, 12Dand the rear surface 12J of the front wall 12E, the grip cover 12defines an internal or interior space 12S. In one embodiment, the gripcover 12 is of uniform construction, although in other embodiments thegrip cover 12 may be formed by securing together two or more componentparts. The grip cover 12 may be formed of one or more conventionalmaterials, and in one embodiment the grip cover 12 is a plasticcomponent covered by a metallic film or coating to simulate a chromehandle. Alternatively or additionally, the plastic grip cover 12 may becovered by one or more colored films or coatings and/or by one or moreclear films or coatings. In still other embodiments, the grip cover 12may be formed of or include one or more coated or uncoated metals ormetal composites.

The handle base 14 illustratively has opposing upper and lower walls14A, 14B respectively and opposing side walls 14C, 14D respectively. Allsuch walls 14A-14D are joined by an elongated rear wall 14G which isillustratively at least partially arcuate to match the at leastpartially arcuate shape of the front wall 12E of the grip cover 12.Between the side walls 14C, 14D, the upper and lower walls 14A, 14B ofthe handle base 14 define a front lip 14L which illustratively definesan arcuate and generally concave section between and relative to twoopposing end sections configured to match the concave section 12I andend sections 12G, 12H of the grip cover 12 such that the front lip 14Lof the handle base 14 receives in contact the rear lip 12F of the gripcover 12 when the grip cover 12 and the handle base 14 are broughttogether as illustrated in FIG. 1. Between the front lip 14L andinterior surfaces of the upper and lower walls 14A, 14B, the side walls14C, 14D and the front surface 14H of the rear wall 114G, the handlebase 14 defines an internal or interior space 14S.

A latch actuator 16 extends rearwardly from the handle base 14 adjacentto one of the side walls 14C, and a pivot mount 18 extends rearwardlyfrom the handle base 14 adjacent to the opposite side wall 14D. Thelatch actuator 16 is illustratively configured to operatively couple toa conventional door latch assembly carried by a door of a motor vehicleto which the handle assembly 10 is mounted (see, e.g., FIG. 10). Thepivot mount 18 is illustratively configured to extend into the door andpivotally couple to one or more structures therein. Movement of thehandle base 14 about the pivot mount 18 illustratively moves the latchactuator 16 to actuate the door latch assembly in a conventional mannerto enable the user to open the motor vehicle door. Two bores 20A, 20Bare formed through the handle base 14; one bore 20A is formed adjacentto the latch actuator 16 and the other bore 20B is formed adjacent tothe pivot mount 18.

Adjacent to the latch actuator 16, the handle base 14 defines aprotrusion 14E between the upper and lower walls 14A, 14B, and adjacentto the pivot mount 18 the handle base defines a protrusion 14F betweenthe upper and lower walls 14A, 14B. Each protrusion 14E, 14Fillustratively extends rearwardly from the handle base 14, and thearcuate rear wall 14G extends between the protrusions 14E, 14F andbetween the upper and lower walls 14A, 14B. As illustrated most clearlyin FIGS. 10-13, the protrusions 14E, 14F extending rearwardly from thehandle base 14 are illustratively sized and configured to contact theouter skin 100A of the motor vehicle door 100 when the door assembly 10is mounted to the motor vehicle door 100, and a space 110 is definedbetween a portion 115 of the outer surface of the outer skin 100A of thedoor 100 and the rear surface 14R of the arcuate rear wall 14G of thehandle base 14. The arcuate profile of the rear wall 14G of the handlebase 14 is, along with sizes and shapes of the protrusions 14E, 14F,illustratively configured to produce the space 110 with a size and shapesuitable to allow one or more fingers and at least a portion of a humanhand 120 to extend sufficiently therein to come into contact with therear surface 14R of the rear wall 14G so that the hand 120 can thengrasp the combination of the handle base 14 and the grip cover 12 withat least one finger extending into the space 110 and wrapped around therear surface 14R of the arcuate rear wall 14G of the handle base 14 in aconventional fashion.

In one embodiment the handle base 14 is of uniform construction,although in other embodiments the handle base 14 may be formed bysecuring together two or more component parts. The handle base 14 may beformed of one or more conventional materials, and in one embodiment thehandle base 14 is a plastic component covered by one or more suitablefilms or coatings. In alternate embodiments, the handle base 14 may beformed of or include one or more other suitable coated or uncoatedmaterials.

The interior space 12S of the grip cover 12 and the interior space 14Sof the handle base 14 together define a space sized to house electroniccomponents when the grip cover 12 and the handle base 14 are securedtogether. Referring now to FIG. 2, the door handle assembly 10illustratively further includes a circuit board carrier 30 to which acircuit board 40 is mounted, and the circuit board carrier 30 andcircuit board 40 are together mounted within the space defined by andbetween the interior spaces 12S and 14S of the grip cover 12 and thehandle base 14 respectively. A sensor cartridge 50 is received withinthe grip cover 12 separately from the circuit board carrier 30 and thecircuit board 40, and a sensor assembly 60, including a sensor 62 (seealso FIG. 4), mountable to the sensor cartridge 50 is electricallyconnectable to the circuit board 40. In the illustrated embodiment, andas will be described in greater detail below, the sensor assembly 60 ismounted to the sensor cartridge 50, and the sensor cartridge 50 is thenmounted to the grip cover 12 such that the sensing surface of the sensor62 is operatively spaced apart from a sensor triggering portion 12K ofthe grip cover 12. In some embodiments, the sensor triggering portion12K of the grip cover 12K is configured to be visually identifiable withthe naked eye. In other embodiments, the sensor triggering portion 12Kmay be visually identified via an illumination source carried within thegrip cover 12. Although the sensor triggering portion 12K is illustratedin FIGS. 1 and 2 as being a portion of the upper wall 12A of the gripcover 12 adjacent to the side wall 12C, it will be understood that thesensor triggering portion 12K may alternatively be located anywherealong the upper wall 12A, e.g., such as the alternate portion 12K′ ofthe top wall 12A adjacent to the side wall 12D as illustrated bydashed-line configuration in FIG. 2, or anywhere along the front wall12E, e.g., such as the alternate portion 12K″ of the front wall 12Eadjacent to the side wall 12C, the alternate portion 12K′″ adjacent tothe side wall 12D or the alternate portion 12K^(IV) of the front wall12E centrally between the side walls 12C, 12D each as illustrated bydashed-line configuration in FIG. 2. In any such alternate positioningof the sensor triggering portion 12K′, 12K″, 12K′″, 12K^(IV) of the gripcover 12, it will be further understood that the sensor cartridge 50 andsensor 60 assembly will be suitably mounted to the grip cover 12 toposition the sensing surface of the sensor 62 so as to be operativelyspaced apart from the wall portion 12K′, 12K″, 12K′″, 12K^(IV). In someembodiments, as will be described below, the sensor triggering portion12K, 12K′, 12K″, 12K′″, 12K^(IV) is made to be at least partiallyflexible so as to deflect inwardly upon application of externalpressure, although in other embodiments the sensor triggering portion12K, 12K′, 12K″, 12K′″, 12K^(IV) may be made substantially rigid. In anycase, the sensor trigger portion 12K, 12K′, 12K″, 12K′″, 12K^(IV) may bemade to be visually distinguishable from adjacent areas of the gripcover 12 by embossing, etching, e.g., laser etching, molding, machiningor otherwise altering the physical appearance of the sensor triggerportion 12K, 12K′, 12K″, 12K′″, 12K^(IV) relative to adjacent areas ofthe grip cover 12, and/or by configuring the sensor trigger portion 12K,12K′, 12K″, 12K′″, 12K^(IV) such that it is at least partiallylight-transmissive so that visible radiation emitted by one or moreillumination sources carried within the grip cover 12 can be seen onand/or externally to the sensor trigger portion 12K, 12K′, 12K″, 12K′″,12K^(IV).

The circuit board 40 illustratively has a number of electronic circuitcomponents mounted thereto. Such electronic circuit componentsillustratively include another sensor (one example 46 of which isillustrated in FIG. 9), sensor signal conditioning circuitry in the formof at least one conventional sensor signal processing circuit 45configured to process sensor signals produced by at least one of thesensors 46, 62 and, in some embodiments, one or more supportingelectronic circuits. In some embodiments, another such electroniccircuit component that may be mounted to the circuit board 40 may be orinclude a conventional processor configured to execute instructionsstored in an on-board and/or externally connected memory unit. Inembodiments which include such a processor, the on-board and/orexternally connected memory unit illustratively has instructions storedtherein which, when executed by the processor, cause it to producecontrol signals to control one or more features associated with the doorhandle assembly 10. In other embodiments, e.g., as illustrated byexample in FIG. 10, such a processor 104 and memory 106 may both belocated outside of the door handle assembly 10, e.g., within the door100 or other area of a motor vehicle, and electrically connected to thecircuit board 40 via suitable wiring 44. In either case, such featuresmay include, but are not necessarily limited to, locking and unlockingof the door handle assembly 10. Alternatively or additionally, suchfeatures may include unlatching of the door handle assembly 10, i.e.,controlling the latch actuator 16 and/or a door latch assembly 102 ofthe motor vehicle to automatically uncouple the latch actuator 16 fromthe door latch assembly 102, latching of the door handle assembly 10,i.e., controlling the latch actuator 16 and/or a door latch assembly 102of the motor vehicle to automatically couple the latch actuator 16 tothe door latch assembly 102, activating and/or deactivating the doorlatch assembly 102 to automatically close and/or open the motor vehicledoor in embodiments in which the door latch assembly 102 is or includesan automatic door opening/closing/assist apparatus and the motor vehicledoor is provided in the form of an access closure with power open/closeassist features, e.g., such as a power lift gate, a power rear door, apower side door, a power sliding door or the like. Alternatively oradditionally still, in embodiments in which one or more illuminationsources is/are mounted to the circuit board 40 and/or elsewhere on orwithin the door handle assembly 10, such features may includeselectively illuminating one or more portions of the door handleassembly 10 and/or one or more portions of the motor vehicle door 100 towhich the door handle assembly 10 is mounted. Alternatively oradditionally still, such one or more features may include processing asequence of detectable changes in signals produced by either or both ofthe sensors, e.g., the sensors 46, 62, and/or other or additionalsensors carried by the assembly 10, and comparing such a sequence to apredefined or pre-set sequence for the purpose of determining whether tolock, unlock, latch, unlatch, close and/or open the door handle assembly10. Alternatively or additionally still, such one or more features mayinclude processing a sequence of detectable changes in signals producedby either or both of the sensors, e.g., the sensors 46, 62, and/or otheror additional sensors carried by the assembly 10, to selectivelycontrol, i.e., activate, deactivate, select and/or position, one or moredriver and/or passenger settings within motor vehicle, e.g., one or moreinterior light settings, one or more entertainment system settings, oneor more climate control settings, one or more seat position settings,one or more steering wheel position settings, one or more rear viewmirror position settings, one or more side mirror position settings, oneor more window and/or sunroof position settings, and/or the like.Alternatively or additionally still, such one or more features mayinclude processing a sequence of detectable changes in signals producedby either or both of the sensors, e.g., the sensors 46, 62, and/or otheror additional sensors carried by the assembly 10, to selectivelycontrol, i.e., activate, deactivate, select and/or position, one or moreexterior structures and/or features of motor vehicle when the vehicle isparked/stationary, e.g., a position of one or more of motor vehicle sidemirrors, e.g., folded against the motor vehicle or unfolded to anoperative position, one or more window and/or sunroof position settings,one or more external motor vehicle lights, or the like.

The circuit board carrier 30 illustratively has a rear wall 32 fromwhich top and bottom flanges forwardly extend to form a pocket 35 sizedand configured to receive the circuit board 40 therein as depicted inFIG. 3. At one end of the pocket 35, the circuit board carrier 30defines a slot 34 sized and configured to receive therein a wiring block64 associated with the sensor assembly 60 (see FIG. 4), and at anopposite end of the pocket 35 the circuit board carrier 30 definesanother slot 36 sized and configured to receive therein another wiringblock 42 which supports and isolates the wiring 44 electricallyconnected to the electronic circuitry carried by the circuit board 40.The wiring 44 is illustratively fed externally from the door handleassembly 10 through an opening 25 defined through the handle base 14. Abore 38A is formed through the circuit board carrier 30 between the slot34 and one end thereof, and another bore 38B is formed through thecircuit board carrier 30 between the slot 36 and an opposite endthereof. The bores 38A, 38B align with the bores 20A, 20B of the handlebase 40, and conventional fixation members 22A, 22B, e.g., screws, aresized to extend through the aligned bores 20A, 38A, 20B, 38B (see alsoFIG. 1) to mount the circuit board carrier 30 to the handle base 14.

Referring now to FIG. 3, the circuit board 40 is shown mounted to thecircuit board carrier 30 to form a circuit board subassembly 70. In theillustrated embodiment, the circuit board 40 is received within thepocket 35 of the circuit board carrier 30 with the wiring block 42electrically connected to the circuit board 40 and to the wiring 44received within the slot 36. Also shown in FIG. 3 is the sensor 62 ofthe sensor assembly 60 mounted to and within the sensor cartridge 50 toform a sensor cartridge assembly 80, and the wiring block 64 associatedwith the sensor assembly 62 received within the slot 34 of the circuitboard carrier.

As illustrated by example in FIG. 4, the sensor assembly 60 includes asensor 62 in the form of an inductive sensor. The sensor 62 includes aplanar substrate 63 having a planar sensor surface 63A upon which asensor coil 65 is disposed and electrically connected to two wires 68A,68B. Each of the wires 68A, 68B connected to the sensor coil 65 passessuccessively through a pair of wiring blocks 66 and 64 respectivelyconfigured to support the wires 68A, 68B in a conventional manner. Anexample embodiment of the sensor carrier 50 is illustrated in FIG. 5 andincludes a planar member 52 defining a planar top surface 50A (seeFIG. 1) and a bottom planar surface 50B, opposite the top planar surface50A, from which surrounding sidewalls 55A-55D extend normally away. Apair of spaced apart interior sidewalls 56A, 56B extend normally awayfrom the bottom planar surface 50B of the planar member 52 adjacent tothe sidewall 55D which is also formed of spaced apart walls to form aslot 54 through the walls 55D, 56A, 56B sized to receive the wiringblock 66 therein. A flange 57A extends away from one side of the planarmember 52 adjacent and generally normal to the sidewall 55B, and anotherflange 57B extends away from an opposite side of the planar member 52adjacent and generally normal to the sidewall 55D. The flanges 57A, 57Bare generally parallel with the planar top and bottom surfaces 50A, 50Bof the planar member 52. A pair of protrusions 58A and 59A extendgenerally perpendicularly away from the bottom and top surfacesrespectively of the flange 57A, and a pair of protrusions 58B and 59Blikewise extend generally perpendicularly away from the bottom and topsurfaces respectively of the flange 57B.

The wiring block 66 is received within the slot 54 formedbetween the sidewalls 55D, 56A, 56B with the wires 68A, 68B extendingthrough the gaps formed between the sidewalls 56A, 56B and the spacedapart portions of the sidewall 55D. In some embodiments, a suitablemounting compound may be disposed in the pocket of the sensor carrier 50to secure the sensor 62 therein. In any case, the sensor 62 is carriedwithin the pocket of the sensor cartridge with the planar sensor surface63A of the sensor substrate 63 spaced apart from and generally parallelwith the planar top surface 50A of the sensor cartridge 50.

With the sensor 62 positioned within the sensor cartridge 50 asillustrated in FIG. 3, the wiring block 64 of the sensor assembly 60 ispositioned in the slot 34 defined by the circuit board carrier 30, andthe wires 68A, 68B extending from the wiring block 64 are electricallyconnected to corresponding electrical terminals 48A, 48B mounted to thecircuit board 40 and electrically coupled to one or more electroniccomponents carried by the circuit board 40. The wiring blocks 64, 66support the sensor wires 68A, 68B and isolate the wires 68A, 68B fromthe sensor circuit board carrier 30 and the sensor cartridge 50respectively.

As illustrated by example in FIG. 7, the spacedapart receptacles 12M, 12N align with the bores 38A, 38B of the circuitboard carrier 30 such that the fixation members 22A, 22B secure thecircuit board assembly 70 to the grip cover 12. It will be understoodthat the fixation members 22A, 22B further secure the handle base 14 tothe grip cover 12 with the circuit board subassembly 70 mountedtherebetween in the space defined by the interior spaces 12S, 14S of thetwo components, and that the handle base 14 is omitted in FIG. 7 toillustrate attachment of the circuit board assembly 70 to the grip cover12.

As further illustrated in FIGS. 6-8B, the interior space 12S of the gripcover 12 defines a slot 90 sized and configured to receive the sensorcartridge 50 of the sensor cartridge assembly 80 therein. The slot 90 isillustratively defined adjacent to the side wall 12C of the grip cover12 and is bordered along its top by a generally planar portion 12L ofthe inner surface of the top wall 12A of the grip cover 12. The portion12L of the inner surface of the top wall 12A is defined opposite thesensor triggering portion 12K between opposing ears 92, 94 projectingdownwardly from the inner surface of the top wall 12A of the grip cover12 into the space 12S. The slot 90 defined between the inner surface 12Lof the grip cover 12 and the opposing ears 92, 94 is sized to receivethe sensor cartridge 50 therein with the slot 54 of the sensor cartridge50 and the wiring block 64 received therein facing away from the sidewall 12C so as to direct the wires 68A, 68B inwardly toward the circuitboard 40. As most clearly illustrated in FIGS. 8A and 8B, theprojections 58A, 58B and 59A, 59B operate to position the top planarsurface 50A of the sensor cartridge 50, and thus the planar sensingsurface 63A of the sensor substrate 63, spaced apart from and generallyparallel with the planar portion 12L of the inner surface of the topwall 12A of the grip cover 12. As illustrated in FIG. 8A, with thesensor cartridge 50 positioned in the slot 90, a space 96A is definedbetween the portion 12L of the inner surface of the top wall 12A and thetop planar surface 50A of the sensor cartridge 50 which, in turn,defines a space 96B between the portion 12L of the inner surface of thetop wall 12A and the planar sensing surface 63A of the sensor substrate63 on which the sensor coil 65 is disposed as illustrated in FIG. 8B.

As further illustrated in FIG. 8B, an electrically conductive film,layer or plate 98 is secured to the portion 12L of the inner surface ofthe top wall 12A so as to be positioned opposite and spaced apart fromthe sensor coil 65 disposed on the planar sensing surface 63A of thesensor substrate 63 when the sensor cartridge 50 carrying the sensor 62is received within the slot 90. Examples of the conductive film, layeror plate 98 may include, but are not limited to, any metallic or otherelectrically conductive film, e.g., chrome or other material(s),painted, deposited or otherwise formed on the portion 12L of the innersurface of the top wall 12A of the grip cover 12, a tape having one ormore electrically conductive layers and/or particles affixed thereto orembedded therein and one or more bonding media, e.g., adhesive or otherbonding media, applied thereto for affixing the tape to the portion 12Lof the inner surface of the top wall 12A, one or more rigid orsemi-rigid electrically conductive sheets or plates affixed in anymanner to the portion 12L of the inner surface of the top wall 12A, orthe like.

In the illustrated embodiment, at least the portion of the top wall 12Adefining the sensor triggering portion 12K is made to be at leastpartially flexible such that the portion 12L of the inner surface of thetop wall 12A is displaced inwardly toward the sensor coil 65 in responseto pressure or force applied to the sensor triggering portion 12K of thetop wall 12A by, e.g., a digit of a human hand. Operation of theinductive sensor 62 is conventional in that the sensor coil 65 isenergized by circuitry on the circuit board 40 to create a sensor outputsignal in the form of an electromagnetic field adjacent to the planarsensing surface 63A of the sensor substrate 63. In one exampleembodiment, circuitry on the circuit board 40 includes a capacitivecomponent electrically connected to the sensor coil 65 through the wires68A, 68B such that the capacitive component and the sensor coil 65together form a resonant circuit. In some embodiments, the resonantcircuit may include at least one or more additional passive componentssuch as one or more resistive elements, although in other embodimentsthe resistive element of the resonant circuit may be provided in theform of inherent resistance in either or both of the capacitivecomponent and the sensor coil 65. In any case, a time-varying signal isapplied to the resonant circuit to produce a time-varyingelectromagnetic field. The size of the sensor coil 65 and the strengthof the electromagnetic field established by the energized sensor coil 65are selected such that the time-varying electromagnetic field extendsacross the space 96B to the electrically conductive film or plate 98.When the portion 12L of the inner surface of the top wall 12A of thegrip cover 12 deflects inwardly a sufficient distance relative to thesurrounding portions of the grip cover 12 in response to correspondingexternal pressure or force applied to the portion 12L of the top wall12A, the electrically conductive film or plate 98 is displaced to withina detection proximity of the sensor coil 65. This results in ameasurable loss in the resonant circuit which can be measured as adetectable change in the output signal of the sensor 62. In oneembodiment, this detectable change in the output signal of the sensor 62is measured as a change in frequency over time, although in alternateembodiments the detectable change in the output signal of the sensor 62may be measured as a change over time in capacitance, inductance and/orresistance, e.g., relative to reference components onboard the circuitboard 40. In some alternate embodiments, the sensor 62 mayillustratively be affixed to or formed on, e.g., printed on, the portion12L of the top wall 12A of the grip cover 12, and the electricallyconductive film, layer or plate 98 may be affixed to or formed on thecarrier 50. In any case, the sensor 62 may, in some embodiments, beconfigured to be responsive to different magnitudes or levels ofpressure applied to the portion 12K, 12K′, 12K″, 12K′″, 12K^(IV) of thegrip cover 12 to produce distinguishably different sensor output signalmagnitudes, and in some such embodiments different pressure(s) appliedto the portion 12K, 12K′, 12K″, 12K′″, 12K^(IV) of the grip cover 12 mayresult in different functions carried out by the door handle assembly 10and/or by one or more actuators or systems of the motor vehicle.

The mounting arrangement of the sensor cartridge 50 to and within thegrip cover 12 as just described is illustratively implemented in someembodiments to minimize or at least reduce the possibility of unintendedor “false” triggering of the sensor 62 due to movement of the grip cover12 relative to the structure(s) to which the sensor 62 may otherwise bemounted. In particular, mounting the sensor cartridge 50 carrying thesensor 62 to the grip cover 12 as just described causes the sensorcartridge 50, and thus the sensor 62, to move along with any movementgenerally of the grip cover 12. As long as any such movement of the gripcover 12 does not cause deflection of the sensor triggering portion 12Lrelative to surrounding portions of the grip cover 12, no detectablechange in the output signal of the sensor coil 65 will occur. It is onlywhen the sensor triggering portion 12L deflects inwardly relative to thesurrounding portions of the grip cover 12 by an amount sufficient tocause a detectable change in the output signal of the sensor coil 65that triggering of the sensor 62 will occur as described above. If thesensor 62 is otherwise mounted to the handle base 14, the circuit boardcarrier 30 or the circuit board 40 and the electrically conductive filmor plate 98 is secured to a portion of the grip cover 12 opposite thesensor 62, any movement of any portion of the grip cover 12 that causesthe film or plate 98 to move sufficiently toward or away from the sensor62 may result in unintended and thus “false” triggering of the sensor62. Although such “false” triggering of the sensor 62 may be more likelyif the sensor 62 is not mounted to the grip cover 12 as described above,this disclosure contemplates embodiments in which the sensor 62 ismounted to one or any combination of the handle base 14, the circuitboard carrier 30 and the circuit board 40.

Referring now to FIG. 9, another sensor 46 is illustratively carried bythe door handle assembly 10 and is configured to detect objectsproximate to or in contact with the rear surface 14R of the arcuate rearwall 14G of the handle base 14. In the illustrated embodiment, such asensor 46 is illustratively provided in the form of an electricallyconductive film, coating or plate 47 facing the front surface 14H of therear wall 14G of the handle base 14 and electrically connected tocircuitry carried by the circuit board 40. In the illustratedembodiment, the film, coating or plate 47 is affixed to the bottomsurface of the circuit board 40, although in alternate embodiments thefilm, coating or plate 47 may be or be affixed to the front or rearsurface of the rear wall 32 of the circuit board carrier 30, and instill other embodiments the film, coating or plate 47 may be or beaffixed to the front surface 14H of the handle base 14 or otherwisedisposed so as to be suitably spaced apart from the rear surface 14R ofthe handle base 14. In any case, the film, coating or plate 47 may beprovided in any of the forms described by example above with respect tothe electrically conductive film, layer or plate 98, wherein any suchfilm, coating, layer or plate material is electrically connected tocircuitry carried by the circuit board 40 as described below.

The film, coating or plate 47 electrically connected to circuitrycarried by the circuit board 40 forms one electrode of a conventionalcapacitive sensor 46. In the illustrated embodiment, portions of therear wall 32 of the circuit board carrier 30 and the rear wall 14G ofthe handle base 14 aligned with outwardly facing surface 47A of thefilm, coating or plate 47 together form a dielectric of the capacitivesensor, and circuitry on-board the circuit board 40 applies atime-varying, e.g., AC signal, to the film, coating or plate 47 whichcauses the film, coating or plate 47 to create a time-varying electricfield. As long as no object is placed sufficiently close to the rearsurface 14R of the rear wall 14G of the handle base 14, the time-varyingelectric field will not measurably change. Placing an objectsufficiently close to the rear surface 14R of the rear wall 14G willinduce a change the electric field produced by the film, coating orplate 47 which can be measured as a detectable change in the outputsignal of the sensor 46. In one embodiment, this detectable change inthe output signal of the sensor 46 is measured as a change in voltageover time, although in alternate embodiments the detectable change inthe output signal of the sensor 46 may be measured as a change over timein current or as a change over time in capacitance, e.g., relative to areference capacitor onboard the circuit board 40. In one embodiment, thesize of the film, coating or plate 47, the amplitude of the time-varyingapplied thereto, the thickness of the dielectric materials and thedielectric constant of the combined dielectric materials areillustratively selected so that at least a portion of a human hand,e.g., one or more fingers, within a detection proximity of the rearsurface 14R of the rear wall 14G of the handle base 14 will trigger thesensor 46. In alternate embodiments, such parameters may be selected sothat at least a portion of a human hand must be in contact with the rearsurface 14R of the rear wall 14G in order to trigger the sensor 46. Inany case, the sensor 46 may, in some embodiments, be configured to beresponsive to different distances of the object, e.g., fingers and/orhand, from the rear surface 14R of the rear wall 14G of the handle base14 to produce distinguishably different sensor output signal magnitudes,and in some such embodiments such different distances of the object fromthe rear surface 14R of the handle base 14 may result in differentfunctions carried out by the door handle assembly 10 and/or by one ormore actuators or systems of the motor vehicle.

Referring now to FIG. 10, the door handle assembly 10 is shown mountedto an entry door 100 of a motor vehicle. In the illustrated embodiment,the latch actuator 16 extends through the outer skin 100A of the vehicledoor 100 and is mechanically linked via a linkage L to a conventionaldoor latch 102 of the vehicle door 100. A door lock and unlock (and/ordoor latch/unlatch) actuator 105 is coupled to the door latch 102. Thedoor lock and unlock actuator 105 is responsive to a lock signal to lockthe door latch 102 and to an unlock signal to unlock the door latch 102(and/or to a latch signal to latch the door latch 102 and/or to anunlatch signal to unlatch the door latch 102). In the embodimentillustrated in FIG. 10, the wiring 44 connected to the circuit board 40of the door handle assembly 10 is electrically connected to a processor104 located within the motor vehicle, e.g., as part of a motor vehiclecontroller or control unit, and the processor 104 illustrativelyincludes or is electrically connected to a memory unit 106. In suchembodiments, the circuitry onboard the circuit board 40 of the doorhandle assembly 10 may or may not include a processor and a memory. Inembodiments in which the door handle assembly 10 does not include aprocessor and a memory, the memory unit 106 illustratively has storedtherein instructions which, when executed by the processor 104, causethe processor 104 to solely control operation of the door handleassembly 10 and the door latch 102. In embodiments in which the doorhandle assembly 10 includes a processor and a memory, such a memory mayinclude instructions stored therein which, when executed by the onboardprocessor, cause the on-board processor to control operation of the doorhandle assembly 10 and the memory unit 106 illustratively has storedtherein instructions, which when executed by the processor 104, causethe processor 104 to control operation of the door latch 102. In stillother embodiments in which the door handle assembly 10 includes aprocessor and a memory, the processor 104 and memory 106 may be omittedand the memory onboard the circuit board 40 illustratively has storedtherein instructions which, when executed by the processor onboard thecircuit board 40, cause the onboard processor to solely controloperation of the door handle assembly 10 and the door latch 102. Thelocking and unlocking actuator 105 will be described below as beingcontrolled solely by the processor 104, under the control ofinstructions stored in the memory 106, although it will be understoodthat such control may alternatively be carried out by a combination ofthe processor 104 and a processor onboard the circuit board 40 of thedoor handle assembly 10 or solely by a processor onboard the circuitboard 40 of the door handle assembly 10. In some embodiments, theprocessor 104 and/or a processor on-board the circuit board 40 of thedoor handle assembly may be operatively coupled, e.g., electricallyconnected, to one or more motor vehicle actuators, devices or systems107 in embodiments in which signals produced by the sensor 46 and/or thesensor 62 are used to control one or more structures and/or features ofthe motor vehicle as briefly described above. In any case, in theillustrated embodiment a bezel 108 is mounted to the vehicle door 100,and the door handle assembly 10 is mounted to the vehicle door 100adjacent to the bezel 108 such that a space or gap 110 is formed betweena portion 115 of the outer surface of the outer skin 100A of the door100 and the rear surface 14R of the arcuate rear wall 14G of the handlebase 14.

Referring now to FIGS. 11-13, operation of the door handle assembly 10will be described. In the illustrated embodiment, the door latch 102 hasa conventional latched condition in which the door latch 102 engages thelatch actuator 16 to maintain the vehicle door 100 closed and whichprevents the door 100 from opening on its own, and an unlatchedcondition in which the door latch 102 releases the latch actuator 16 toallow the vehicle door 100 to be opened for vehicle ingress and egress.The door latch 102 illustratively has a locked state and an unlockedstate as is also conventional, which are controlled by the actuator 105.In the unlocked and latched state of the door latch 102, the door 100 isclosed and a user may grasp and pull the combination of the handle base14 and the grip cover 12 outwardly away from the door 100 to cause thelatch actuator 16 to unlatch the door latch 102 so that the user mayopen the door 100, e.g., by continuing to pull outwardly on thecombination of the handle base 14 and grip cover 12. In the locked andlatched state of the door latch 102, the latch actuator 16 is preventedfrom unlatching the door latch 102, thereby preventing the door 100 frombeing opened. Such operation of the latch actuator 16 and the door latch102 is conventional.

The sensors 46, 62 carried by the door handle assembly 10 illustrativelyprovide for controlled locking and unlocking of the door latch 102 asjust described. In the illustrated embodiment, the sensor 46illustratively provides for controlled unlocking of the door latch 102and the sensor 62 illustratively provides for controlled locking of thedoor latch 102, although in alternate embodiments the foregoingfunctions of the sensors 46, 62 may be reversed. As illustrated in FIG.11, the door latch 102 in its locked state may be unlocked by extendingat least a portion of a hand 120 into the space 110 between the rearsurface 14R of the rear wall 14G of the handle base 14 and the portion115 of the outer skin 100A of the door 100. In one embodiment, thesensor 46 is illustratively configured to be triggered when the portionof the hand 120 is within a designed distance of, but not in contactwith, the rear surface 14R. In alternate embodiments, the sensor 46 maybe configured to be triggered when the portion of the hand 120 is incontact with the rear surface 14R of the rear wall 14G of the handlebase 14. In any case, the output signal of the sensor 46 is monitored bythe processor 104, under control of instructions stored in the memory106, and such triggering of the sensor 46 creates a detectable change inthe output signal of the sensor 46 to which the processor 104 isresponsive to control the door latch 102 to its unlocked state.Thereafter, the door handle assembly 10 may be actuated as illustratedin FIG. 12 and as described above to cause the latch actuator 16 tounlatch the door latch 102 so that the door 10 may be opened for ingressor egress. In some embodiments, the processor 104 may be additionally oralternatively responsive to triggering of the sensor 46 to control thedoor latch 102 to its unlatched state. Alternatively or additionally, inembodiments in which the door latch assembly 102 is or includes anautomatic door opening/closing/assist apparatus and the motor vehicledoor is provided in the form of an access closure with power open/closeassist features, e.g., such as a power lift gate, a power rear door, apower side door, a power sliding door or the like, the processor 104 maybe additionally or alternatively responsive to triggering of the sensor46 to control the door latch 102 to activate the door latch assembly 102to automatically open the motor vehicle door.

As illustrated by example in FIG. 13, the door latch 102 in its unlockedstate may be locked by applying a force or pressure, e.g., by a digit ofa user's hand 120, to the portion 12K of the grip cover 12 sufficientlyto cause the sensor 62 to be triggered as described above. The outputsignal of the sensor 62 is monitored by the processor 104, under controlof instructions stored in the memory 106, and such triggering of thesensor 62 creates a detectable change in the output signal of the sensor62 to which the processor 104 is responsive to control the door latch102 to its locked state. Thereafter, the door latch 102 will preventactuation of the door handle assembly 10 from causing the latch actuator16 to unlatch the door latch 102. In some embodiments, the processor 104may be additionally or alternatively responsive to triggering of thesensor 62 to control the door latch 102 to its latched state.Alternatively or additionally, in embodiments in which the door latchassembly 102 is or includes an automatic door opening/closing/assistapparatus and the motor vehicle door is provided in the form of anaccess closure with power open/close assist features, e.g., such as apower lift gate, a power rear door, a power side door, a power slidingdoor or the like, the processor 104 may be additionally or alternativelyresponsive to triggering of the sensor 62 to control the door latch 102to activate the door latch assembly 102 to automatically close the motorvehicle door.

In some embodiments, triggering of at least one of the sensors 46, 62may cause the processor 104 to control other aspects of the door handleassembly 10. For example, in some embodiments, the circuit board 40, thecircuit board carrier 30, the handle base 14 and/or the grip cover 12may have one or more illumination sources mounted thereto, and in suchembodiments the instructions stored in the memory 106 may includeinstructions which, when executed by the processor 104, cause theprocessor 104 to activate one or more such illumination sources inresponse to detected trigger of either or both of the sensors 46, 62.

Alternatively or additionally, the processor 104 may be programmed tocontrol the state of the door latch 12 based on sequential triggering ofat least one of the sensors 46, 62 according to a predefined orprogrammable triggering sequence. As one specific example, if triggeringof the sensor 46=1 and triggering of the sensor 62=2, the instructionsstored in the memory 106 may include instructions which, when executedby the processor 104, cause the processor 104 to control the door latch102 from its locked state to its unlocked state (and/or to control thedoor latch 102 from its latched state to its unlatched state and/or tocontrol the door latch 102 to automatically open the vehicle door) upondetection of the sensor triggering sequence 2212. In some embodiments,the sensor triggering sequence may be a predefined sequence, and inother embodiments the instructions stored in the memory 106 may includeinstructions which, when executed by the processor 104, cause theprocessor 104 to execute a programming mode in which a “private”triggering sequence may be programmed by a user. In some suchembodiments, different users of the vehicle may program differentprivate triggering sequences and in such embodiments the processor 104may be configured to control the door latch 102 from its locked state toits unlocked state upon detection of any such programmed triggeringsequence. In any case, the processor 104 may be programmed in some suchembodiments to control the door latch 102 from its unlocked state to itslocked state (and/or to control the door latch 102 from its unlatchedstate to its latched state and/or to control the door latch 102 toautomatically close the vehicle door) upon detection of a singletriggering of the sensor 62 as described above, or upon detection of apredefined or programmed sequence of sensor trigger events of either oneor both of the sensors 46, 62 as just described.

In some embodiments, triggering of at least one of the sensors 46, 62,either singly or sequentially, may cause the processor 104 to controlother aspects of the motor vehicle as described briefly above. In suchcases, the processor 104 (and/or the processor carried on the circuitboard 40, if any) may be configured to process a single trigger signalor a sequence of trigger signals produced by either or both of thesensors, e.g., the sensors 46, 62, and/or other or additional sensorscarried by the assembly 10, to selectively control, i.e., activate,deactivate, select or control one or more actuators, devices or systems107 to thereby activate, deactivate, select, control and/or position oneor more driver and/or passenger settings of the motor vehicle. Examplesof such one or more inter-vehicle driver and/or passenger settings ofthe motor vehicle may include, but are not limited to, one or moreinterior light settings, one or more entertainment system settings, oneor more climate control settings, one or more seat position settings,one or more steering wheel position settings, one or more rear viewmirror position settings, one or more side mirror position settings, oneor more window and/or sunroof position settings, and/or the like.Examples of such one or more external vehicle driver and/or passengersettings of the motor vehicle may include, but are not limited to, oneor more exterior structures and/or features of motor vehicle when thevehicle is parked/stationary such as a position of one or more of motorvehicle side mirrors, e.g., folded against the motor vehicle or unfoldedto an operative position, one or more window and/or sunroof positionsettings, one or more external motor vehicle lights, or the like.

While the disclosure has been illustrated and described in detail in thedrawings and foregoing description, such an illustration and descriptionis to be considered as exemplary and not restrictive in character, itbeing understood that only illustrative embodiments have been shown anddescribed and that all changes and modifications consistent with thedisclosure and recited claims are desired to be protected. For example,while the door handle assembly 10 illustrated in the attached figures isdepicted, and has been described, as having a capacitive sensor 46positioned adjacent to the rear surface 14R of the wall 14G of thehandle base 14 and an inductive sensor positioned adjacent to a portionof a wall of the grip cover 12, it will be understood that embodimentsin which both sensors 46, 62 are capacitive sensors, in which bothsensors 46, 62 are inductive sensors, and/or in which the sensorpositioned adjacent to the rear surface 14R of the rear wall 14G of thehandle base 14 is an inductive sensor and the sensor positioned adjacentto a portion of a wall of the grip cover 12 is a capacitive sensor, areall contemplated by this disclosure.

Likewise, while the door handleassembly 10 has been described as having a sensor positioned adjacent toa portion of a wall of the grip cover 12 which may be triggered tocontrol the door latch 102 from its unlocked state to its locked state,this disclosure contemplates embodiments in which such a sensor may betriggered to control the door latch 102 from its locked state to itsunlocked state. As still another example, while the door handle assembly10 has been described as including two sensors mounted separately fromone another, this disclosure contemplates embodiments in which bothsensors are mounted together, e.g., on one or more substrates mounted toa sensor cartridge received in a slot formed in the grip cover 12 whichextends the length, or at least part of the length, of the internalspace 12S thereof, on one or more substrates mounted directly to thegrip cover 12, or on one or more substrates mounted to the handle base14. As yet a further example, while the door handle assembly 10 isillustrated in FIGS. 10-13 and described as being operatively mounted toa motor vehicle door 100, it will be understood that the door handleassembly may alternatively be mounted, in whole or in part, to otherstructures of the motor vehicle including, for example, but not limitedto, a sliding motor vehicle door, a rear hatch, trunk or swinging doorof the motor vehicle or a stationary portion of the motor vehicle suchas, any of the so-called “A,” “B” or “C” pillars of the motor vehicle.
